Nozzle



Patente-d May 21, 1935 .Thispinvention relatesto injection circulators and more particularly to nozzles, although. cer-i` tain z features vthereof may be employedwith equal-advantage for'other purposes. i f t" ltcontemplates more'especially the provision of -imeans `forY injecting Va medium such as "steam into a system for effecting circulation throughf out `the interiorof atank4V thereby elevating y theitempera'ture of its contents incidentV to ef- 1`o fecting thorough circulation without any. appreciable accompanying noise. A i

Steam or other injectingfmediums'f are corn--l monly resorted to A'in breweries,` laundries and similar enterprises whereircirculation within a tank is of importance'inconjunctionwith-temperature` elevation o f its contents. This injection is usually accomplished by substantialandA in consequence thereof;y

Still another object vis'theprovision of 'a simple nozzle -to eiect complete commingling of the conl tents Within a confining tank incident to imparting an elevated temperature thereto Without any appreciable noise. v f

A still further object is to provide a steam injector having means in association therewith for diifusing and guiding the medium therethrough Without any appreciable noise.

Still a further object is to provide a nozzle having inclined apertures for directing the steam therethrough in conjunction with a conical tip disposed axially thereof for effecting the passage without any appreciable noise.

Other objects and advantages will appear from the following description of an illustrated embodiment of the invention.

In the drawing:

Figure 1 is a View in elevation of a beer tank having an injecting nozzle embodying features of the present invention.

Figure 2 is an enlarged fragmentary sectional view of the tank and the nozzle.

tank I 0 is of cylindrical :conguration `and of l0' wooden construction; however, such may vary withinawide range depending u'ponthe particu-- larlpurpose forfvvhichit is employed orcdesired.` lnthecase of 'a beer tank; ljthe Walls are re-` inforced=` by* means of rods II vhaving couplers l5 |21whichvare'fadjustable and` in threaded connection `.With `the "extremities of i, the rods J `I I 'to enable `the ytightening thereof from time to' time.` This renders the tankI 0 'leaky-'proof andenables the' maintenance thereofllin such condition over 20 extended periods.'v Steam coilsfI3 maybeutilized inA enveloping lrelationrvvith thetank I0 so'as to elevate'fthe 'temperature thereof I or` to control such within commercial requirements A'for anyde-` sired purpose. 1 The structure-'thus far described 25 l forms no part of the invention and merely serves toillustrate the purpose and manner of `installation of a 'nozzle of the type embodying features of the presentinvention.' i In its preferred embodiment, the nozzle com- 30 prises a tubular member I4 which terminates in a polygonalfiia'nge I 5 `for application tothe interior wall ofthe tank IIL The interiorsurface of the memberf lis'threaded as at I6so as to'be engaged by a' pipe coupler IT that has a correspond- 35 ingly threaded extremity I8 serving as a complement thereof. The pipe member I1 is provided with a peripheral flange I9 that retains a gasket 20 in position against the interior wall of the tank III so as to be in hermetically sealed engage- 40 ment therewith to direct the passage of steam or any other circulating medium therethrough. A supply of steam is directed to a pipe 2 I in threaded engagement with the boss 22 lof the flange I9, thereby directing steam .to the interior of the 45 tubular member I4 for injection within the interior 23 of the tank I0.

- As shown, the tubular member I4 terminates in an enlarged tubular member 24 integrally or otherwise associated therewith to present a peripheral shoulder 25 beyond the confines of the tubular member I4. A rather thick Wall 26 separates the interior of the tubular member I4 from the interior of the tubular member 24, there being' a plurality of radially disposed and inclined apertures 21, in this instance four, in the wall 26 to establish communication between the interiors of the tubular members I4 and 24. The apertures 21 are inclined, in this instance, at an angle of substantially 32 and diverge from the interior of the tubular member I4 to the interior of the tubular member 24 so as to diffuse the steam that issues therethrough.

In order yto eiect the passage of the steam through `the tubular member il .for injection within the interior 23 of the tank IIJ without any appreciable noise which is an important factor,` a conical tip 28 is formed axially of the apertures 21 and the base thereof extends substantially to the entry orices thereof seas to diuse andguideV the steam for passage therethrough with mum noise. The tip 28 may be integrally formed in connection with the wall 26 but 'preferably comprises a detachable plug that has threaded shank 29 and a polygonal extremity 30 so as to extend through .a correspondingly `threadedatpertm'eprovided in the wall 16. Y f

`With this arrangement, the position of the con-- ical tip 28 may be varied to effect the proper diitusion `and passage of tht-:steam wiirminimum noise and obstruction. So that the contents of the tank itl 'may be circulated in consequence of the injection of the steam through the apertures 21, the peripheral shoulder is provided with -a plurality of .apermi'es Min this instance four., that are curvedto correspond with :the foongm'ation of :the shoulder 25 fand-.to comprise the largest possible area'thereofso that the tank contents pass therethrough and establish 4circulation through the eiort and urgeimparted by .the steam issuing through the lapertures 21 for eommingling with vthe tank contents. This aiTords proper circulation, mixing, temperature elevation, andsuch is effected with :noise characteristics that are .substantial and Avery annoying with the use of the customary injectors or nozzles.

Various changes :may .made :the embodiment of the invention speciiically described without from vorA sacricing any of the advantages of the invention as deiined in circulation of the surrounding medium, there being inclined apertures extending between said tubular members to establish communication for steam or other medium passage from one to the other, a conical tip extending axially within said rst named tubular member to diiuse and direct the steam through said inclined apertures, and means for connecting a pipe line to the entrant oriiice of saidfirst named tubular member for directing the injecting medium through said inclined apertures to said enlarged tubular memv Joer.

In a device of the character described, the combination with a tubular member defining a passage, of an enlarged tubular member formed axially of said iirst named tubular member to present a peripheral shoulder forwardly of the entrant orice of said iirst named tubular member, there being inclined apertures extending between said tubular members to establish communication for steam or other medium passage from-one to the other, there apertures in said shoulder for Vcirculation of the surrounding medium therethrough responsive to said steam injection, an adjustable conical tip extending axially within said iirst named tubular member to diiuse and direct the steam through said inclined apertureaand means for connecting va pipe line to the entrantlorice of said first named tubular member for directing the injecting medium through said inclined apertures to said inla-rged tubular member.
